Radiators not heating up properly? This could be why...

Have you noticed a lag in the heat up time with your boiler or one of your radiators not producing as much warmth as it once did?

It could just be as simple as built up magnetite in your pipes - basically black sludge which blocks water from circulating around the system as it should. It's a fairly common issue and affects both Gas and Oil central heating systems.

You can see an example of what this looks like here - taken from a recent job in Cheshire:

Is it harmful?

Potential issues you can get from this are:

  • Blocked pipes

  • Radiators not giving enough heat

  • Radiators not working at all

  • Unusually slow heating kick up time (over 5-10mins)

  • In more extreme cases a damaged boiler.

What is the solution?

Luckily, if caught in time, a simple power flushing of your heating system can get rid of this build up and get your boiler working efficiently again. However, if left untreated for a long period of time, the build up of 'sludge' can become quite a problem, and may require some re-piping work to replace any areas too badly blocked.

The biggest potential risk is if the sludge works it's way through the heating system and into the boiler itself. This could cause damage to some of the components within the boiler, which would then need replacing. Worst case scenario: it's new boiler time.

Prevention is key

The best way to try and avoid a build up of any kind is a regular system cleanse, once every 5-10 years dependant on the size of your house/heating usage. You can also have a system filter installed for extra protection - this uses a magnet to attract any build up of magnetite, filtering the water before it reaches the boiler.
